unsound - there are real advantages for outboarding, and time may lead there. I have laid out the crossovers in outboard configuration. However, there are problems along with advantages. The separate enclosure flunked the appeal census by a wide margin. The electromagnetic field interactions of coils would require a fairly large enclosure. And the wire-cable between the XO and the drivers is a critical link that invites unknowns because an external XO might be moved, adding additional cable of unknown parameters, which could seriously impact the signal at the drivers. That cable snake requires engineering-development that I am not presently prepared to provide. Many of those disadvantages could be overcome by piggy-backing the XO on the back of the cabinet, but that reintroduces some of the problems.
All things considered, including my limited time and resources, led to starting with the XOs remaining internal, which also preserves the classic Thiel value of simplicity of use.
